German Breeding Rings or GBR (“Aufzuchtringe”) are a genius invention by several of my German pleco friends: GBRs are floating egg and fry rearing incubators with integrated mini-jetlifter that supplies them continuously with fresh water. Intended to raise small batches of almost any type of fry, the bottom is covered with a 153 mesh/30 micron nylon gauze (which is replaceable if need be but rinses very well). That means you can feed your fry with Artemia nauplia (baby brine shrimps), rotifers, copepods, and powdered dry food without flushing the food out. Because GBRs float on the surface of a bigger tank, the water quality remains much more stable and the babies do not disperse over a large area, which would make them difficult to feed adequately.
The GBR have been conceived and improved over the past 3 years via several prototypes and redesigns to make the most convenient and long lasting gadget possible. I have tested these myself for over a year and successful breeders such as Robert Budrovcan, Ernsti Schmidt, Andy Tanke, Ingo Seidel, and others have contributed to optimizing them. For example, there are no corners that tend to accumulate waste or areas that have no flow, since the bottom is porous.
